Abstract

Penelitian tentang pergeseran tanah (ground shear strain) di Kota Palu menggunakan data mikrotremor telah berhasil dilakukan.  Penelitian ini bertujuan untuk menentukan nilai dan keadaan pergeseran tanah di Kota Palu. Daerah penelitian ini meliputi 3 kecamatan yaitu Kecamatan Mantikulore, Kecamatan Palu Barat, dan Kecamatan Palu Timur. Tahapan penelitian menggunakan data sekunder mikrotremor berupa frekuensi dominan (f0) dan faktor amplifikasi (A0). Indeks kerentanan seismik (Kg) dan nilai percepatan getaran tanah maksimum Peak Ground Acceleration (PGA) diperoleh dengan menggunakan nilai f0 dan A0 tersebut.  Hasil analisis f0, A0, perhitungan Kg dan PGA maka didapatkan nilai pergeseran tanah (?). Hasil penelitian ini menunjukkan bahwa besar nilai pergeseran tanah (?) di Kota Palu berkisar antara 4,66 x 10-6 sampai 1,00 x 10-4. Keadaan tersebut, akan menyebabkan sebagian besar Kota Palu mengalami keretakan atau pergeseran jika terjadi gempabumi dan sebagian kecil hanya mengalami getaran tanah

Abstract

Indonesia is an agricultural country where the livelihood of the majority of the population is farming. Geographically, Indonesia is an archipelagic country that has enormous natural potential, both in the marine and agricultural fields. The agricultural sector is a sector that has an important role in improving the welfare of the entire population of Indonesia. Rice fields in Blang Beurandang Village still rely on irrigation from using rainwater to meet irrigation water needs. To increase rice yields, an irrigation network is needed that can flow water to the rice fields. It is necessary to conduct a feasibility study on the irrigation to be built so that it can be calculated from an economic point of view whether the project is feasible or not. This feasibility study is equipped with an analysis using the first method; Net Present Value (NPV), the second is the Benefit Cost Ratio (BCR) analysis, the third is the Internal Rate of Return (IRR), and the fourth is the Break Event Point (BEP). The results of this study are the value of the investment cost of the construction project or the initial capital of the irrigation canal which is IDR. 2,088,058,500, and the value of the operational and maintenance costs is IDR. 9,578,250 per year. The results obtained that NPV was IDR. 30,614,330, BCR was 1.01%, IRR was 5.88% > 5% and BEP occurred in the 22nd year and the 7th month. Based on the calculation results obtained from these four methods, it shows that the irrigation channel construction project has met the eligibility requirements and the project can be implemented or built. This means that the construction of irrigation networks in the village is feasible.

Abstract

 The scheduling method that is often used in project planning in a deterministic way is the CPM method, the PERT method. However, in reality, uncertainty is often found in project completion, in accordance with the characteristics of a construction project that has a high level of risk. One of the methods used to determine the estimated project time is the monte carlo simulation method. The monte carlo simulation is a statistical sampling technique used to estimate solutions to quantitative problems. The research was conducted on the construction project of the Public Service Center (PSC) building in Krueng Sabee District, Aceh Jaya Regency. The purpose of this study is to determine the probabilistic method of scheduling and to explain the application of the monte carlo method for scheduling. The data used in this study are secondary data in the form of interviews and project implementation time schedule (curve S). Based on the monte carlo simulation that has carried out the distribution of completion on a public service center building construction project, the minimum value of the total project duration is 86.40 days, the maximum value of the total project duration is 105 days, and the mean value is 96 days. So the project can be completed within 96 days of the 100 plan days. So it can be concluded that the project is completed 4 days faster than the 100 day plan. Based on the above explanation, the Monte Carlo simulation is not significant enough to reduce the project duration, so that more significant work can be added or overtime. Keywords— Scheduling, Probabilistic, Simulation, Monte Carlo
